Yintoni ubunzima 1 m3 of eziphathekayo

Okwangoku, eminyaka emininzi eyadlulayo, le ikhonkrithi yeyona ixhaphakileyo ekufanisweni yokwakha. Oku kusetyenziswa xa usenza iintlobo ngeentlobo imisebenzi yokwakha - yi overhauls ukwakha izakhiwo. Noko ke, ukuba enze nawuphi na umsebenzi into yokuqala ufuna ukubala ubungakanani izinto ezifunekayo, kuthathelwa ingqalelo iimpawu zayo. Umzekelo, abakhi amaninzi nzima ukufumanisa nobunzima cubic meter kuyo. Ngoko ke, eli nqaku igxininisa umbuzo wokuba yintoni na ubunzima 1 m3 of eziphathekayo.

Ukususela oko kuxhomekeke ubunzima eziphathekayo

Okokuqala, kufanele kuqatshelwe ukuba abakhi musa ukusebenzisa into efana "ubunzima ezithile eziphathekayo." Oku kubangelwa yinto yokuba izinto zokwakha kumafa yayo singaqulatha ezahlukeneyo izakhi babe iintsimbi ezahlukeneyo.
Ngenxa yoko, njengokuba lokufaka zingasetyenziswa:
• luhlalu.
• grabile.
• udaka Ukwandiswa kunye nabanye.
Nokuba, ngenxa yokulungiselela ngodaka eziphathekayo isetyenziselwa ukwakhiwa enye, ubunzima 1 m3 of eziphathekayo nga zinokohluka kwiimeko apho lokufaka iye amaqhezu ezahlukeneyo. I elikhulu iqhezu, imigodi ezinkulu kulo myalezo, kwaye ngokufanelekileyo, ubunzima ngaphantsi.

Noko ke, abakhi nangoku unomdla iimpawu ubunzima, ngenxa ixabiso le index kuxhomekeke ngeempawu ezininzi izinto ephunyeziweyo. Umzekelo, zisebenza ngenxa yezi data, ekubaleni ubunzima , kwaye ukhethe ukwenza iziseko kwiintlobo ezahlukeneyo zomhlaba. Kukwasebenza kwezinye izinto umthwalo-langa.

Ekusebenzeni abakhi basebenzisa i parameter, ebizwa ngokuba "ubuninzi mninzi." Kodwa lo msebenzi akanalo ixabiso rhoqo. Ukongeza, izibalo kufuneka athathe ingqalelo ubunzima ulwelo isicelo ekulungiseleleni sisombululo.

iintlobo eziphathekayo

Xa uhlobo Umatshini, eli izinto zokwakha ezahlulwe kwi isamente, ikalika, shlakoshchelochnyh, Musiqisi kunye nabanye. Xa injongo ezahlulwe concretes njengesiqhelo (ngenxa yoluntu yokwakha mveliso), ekhethekileyo (kuba iindlela, zokuhombisa, zokwambathisa, hydraulic) kunye nenjongo ekhethekileyo (iikhemikhali enganyangekiyo, isandi abaninzi, ubushushu-resistant ukukhusela kumaza enyukliya, njalo njalo).

iimpawu eziphathekayo

Njengoko lwesalathisi esisiseko eziphawula izinto, kusetyenziswa amandla compressive. Olu phawu kugqiba udidi eziphathekayo, eboniswe unobumba "B" (isiLatin), kwaye amanani ebonisa (kg / cm²) umthamo umthwalo. Umzekelo, B25 ixabiso-kubonisa ukuba le udidi ngekhonkrithi lwenzelwe umthwalo we-25 kg / cm. Xa kubalwa izalathisi kokuqinisela zithinteli kufuneka athathe kwi imiba ingqalelo. Umzekelo: ukwakhiwa concrete B25 grade ngeqondo ukungavumelani kwe ukutshintshatshintsha ka-13.5 ekhulwini ukumelana umthwalo 327 kg / cm, nto leyo ilingana M350 amandla brand. V3,5 class amandla olungqamana amandla brand M50, B10 - M150, B30 - M400 no B60 - M800.

Ezinye ngokwezalathi ezibalulekileyo ziquka ukumelana iqabaka eziphathekayo, amandla flexural kunye nokumelana amanzi. ukumelana uFrost luchazwa ngu «F» kunye nenani 50 ukuya 500, nto leyo ethetha inani yokutshintsha ukusuka ithi uzimele thawing kunye umva oluya ukumelana eziphathekayo. Kuba index ukumelana amanzi asetyenziswa ileta «W» kunye nenombolo ukususela nge-2 ukuya ku-12, nto leyo ebonisa uxinzelelo lwamanzi, nto leyo exhasa isampuli grade ikhonkrithi ngohlobo njengesilinda.

Ukuzimisela ubunzima

data Reference kangangokuba ubunzima womthamo le ngesamente ezichazwe SNP № II-3. Lo mgangatho ikhankanya ubunzima eqikelelwayo kwiintlobo eziphathekayo ngokuxhomekeke kuhlobo lokufaka ngayo. Kuye ezinobunzima itafile eziphathekayo ungabona kuyo ukuba iimveliso eziphathekayo luphawulwa ezixineneyo isambuku (kg / m3) 2500 eziphathekayo kunye lokufaka ngokohlobo amahlalutye okanye amatye nakhandiweyo - 2400, ngokusekelwe ngodongwe eyandisiweyo ye kwandiswa isanti ngodongwe - 500-1800, ngokusekelwe perlite - 800-1000. Ngenxa yoko, i-eziphathekayo ovundileyo iphawulwa ezixineneyo isambuku ka 300-1000 kg / m3. Kakade ke, ubunzima 1 m3 of eziphathekayo inophawu umlinganiswa ilingane, kodwa ezi data afaneleka kahle ukuba iinjongo zokuhlala. Emva kokuba yonke idatha echanekileyo ukuya kilograms ezimbalwa awukwazi ukunika nayiphi na iakhawunti.

Weight eziphathekayo kuxhomekeke brand

Abakhi zidla kumiselwa ngokobunzima 1 m3 of eziphathekayo, kuxhomekeka kwibanga. Heavy iintlobo zawo luphawulwa uqikelelo zilandelayo. Weight eziphathekayo M200 yi 2430 kg / m3. Ukuphawula M100 Ungasebenzisa ixabiso ka 2495 kg / m3. Weight eziphathekayo M300 - 2390, yaye amanqaku M400 kunye M500 kungathatha amaxabiso 2375 no 2300 kg / m3, ngokulandelelana.

Ngenxa yoko, kweli nqaku amaxabiso ubuninzi ingasetyenziswa esondele izibalo zobunjineli kwi yokulungisa imveliso kunye nokwakhiwa imisebenzi.
